It showed that the peroxidase isozyme zymogram and the soluble protein electrophoretogram of latex C-serum could not clarify the interaction between the rootstock and scion of grafted rubber tree.

Maleic anhydride grafted natural rubber (MNR) was used as modifier, and its effect on the mechanical properties and thermal property of waste newspaper flour (PF) filled PVC composites was studied.

In natural rubber cultivation, planting materials adopted are the high yielding Grafted Hevea Brasiliensis.
